LINK FOR CONVEYER-CHAINS.

Specification of Letters Patent.

Patented May 16, 1911.

Application filed June 21, 1910. Serial No. 568,209.

To all whom it may concern:

Be it known that 1, PETER IGRIOKSON, a

citizen of the United States, residing at Minneapolis, in the county ofHennepin and State of Minnesota, have invented a new and useful Link forConveyer-Chains, of which the following is a specification.

The link which is the subject of the present invention is designedprimarily for conveyer chains handling lumber, and it is the object ofthe invention to provide an improved form of link for a conveyer of thiskind, by means of which the lumber will readily pass onto the conveyor,and is effectually prevented from stopping if it encounters trash andother obstructions.

With this object in view, the invention consists in a novel constructionand arrangement of parts to be hereinafter described and claimed.

The invention is illustrated in the accompanying drawing forming a partof this specification, in which drawing Figure 1 is a plan view of afragment of a conveyor chain showing one of my improved links. Fig. 2 isa longitudinal section of the links, and Fig. 3 is an end view thereof.

The conveyor to which the invention is applied carries the lumber fromthe edger to the trimmer, and is generally known as the transfer. Thisconveyer is usually formed of a series of parallel chains composed oflinks of the roof top type. The conveyor is decked up so that the chainsproject above the deck or floor just sufficiently to take the lumber. Ina conveyer of this kind, the lumber frequently stops on account of trashcollecting on the floor, and to eliminate this objection, the presentinvention has been designed.

In the drawing, 5 denotes a series of roof top links connected to form'a chain, a series of which, as already stated, are placed side by side,to form the conveyer.

My link is interposed in the chain at suitable intervals. This link isalso of the roof top type, it comprising a top 6, and sides 7, from oneend of which project ears 8 between which extends a cross bar 9 fittingbe tween the side walls of the adjacent links, a pin 10 passing throughsaid parts forming the connection between the links. The top or roof ofthe link slopes downwardly in opposite directions from the center.

In the top of the link, intermediate its ends, is an openin 11 throughwhich pro jects a roller 12. Between the side walls 7 of the link,extend transverse webs 13, which are suitably spaced apart, and betweenwhich the roller 12 is located. These webs carry an axle 1 1 on whichthe roller is journaled. The axle of the roller extends parallel to thelongitudinal axis of the link, and the roller projects a sufficientdistance above the top or roof of the link so that it may engage thelumber to be transferred or conveyed.

It will be noted that the roller is mounted transversely with respect tothe link, which is for the purpose of facilitating the entry of thelumber onto the conveyor, the same dropping on the 'conveyer from oneside thereof. The rollers act as lugs to take hold of the lumber andslide the same forwardly to the trimmer, after being deposited on theconveyor from the edger. As already described, the chains travel closeto the floor or deck of the transfer, in view of which the lumber isfrequently stopped if there is an accumulation of trash or rubbish onthe floor. This stoppage of the lumber is entirely prevented by therollers 12, as they come behind the lumber, and positively push the sameforwardly past the obstruction.

\Vhat is claimed is:

1. A conveyer chain link having a closed top, and a roller carried bysaid link, and projecting from the top thereof, the axle of the rollerextending parallel to the longitudinal axis of the link.

2. A conveyor chain link having a closed top, and an opening in saidtop, transverse webs below the top of the link, an axle carried by saidwebs, said axle extending parallel to the longitudinal axis of the link.and

3. A conveyer chain link having a closed PETER sianticlinal top, and aroller carried by the Witnesses:
